Redis implementation of distributed queue Analysis _redis

What is Redis?

Redis is a simple, efficient, distributed, memory-based cache tool.

Assuming a good server, provide key-value caching services over a network connection (similar to a database).

Simple, is the outstanding characteristic of Redis.

Simple to ensure that the core functions of stability and excellence.

Installation and configuration of Redis

Under Linux system:

Apt-get Install Redis-server

Under Windows:

Download link

Download the install MSI file just fine.

Configuring Master-Slave synchronization

You need to implement a distributed queue, at least one master (192.168.45.1) and one slave (192.168.45.130)

Linux default configuration file in/etc/redis/redis.conf

Master configuration:

bind 127.0.0.1

Slave configuration:

slaveof  192.168.45.1 6379

Then you can start the redis-server on each host separately.

Message Queuing mode

Pictures from the network, invasion and deletion

Use the Redis list type to save the data, and the queue takes the left-right out mode to guarantee the order of the queue messages.

Manipulating Redis data using Python

Import Redis

r= Redis. Redis (host= ' localhost ', port=6379, db=0) r.set ('
user ', ' Ioiogoo ') r.get ('
user ')
r.lpush (' queue:1 ', ' Task1 ')
r.brpop (' Queue:1 ', 3)
